We can use Flow for both importing and exporting data with CDS. In addition, we can use it for both standard and custom entities. As for sources, the list of connectors is continuously growing. What does that mean? We can actually synchronize data between various application using CDS.

Note that, while we’re doing this, we’re following a typical scheduled ETL flow. This is not a synchronization service. One of the biggest differences is the fact that no deletes are supported. We can create records, update records, but have no ability to capture delete.
